See if you can startup in Recovery Mode and reinstall Mac OS.
Thanks for the help, but it does not help. the monitor is black and the apple is burning in the center.
I wanted to do it, but I have no memory and now I do not know what to do
Follow the steps in the Support Topic I linked to. If it does not startup, then bring it in for service.
Startup holding the Command and Option keys, that should put your Mac into Recovery Mode. Then choose to reinstall Mac OS. If that does not work, then bring it in for service.
help me please! when you start working with my macbook, the monitor is black and there is an apple on it! what should I do? who knows? Thank you!
